The violations are alleged at the Grab-N-Go espresso stands at 2030 Broadway and 333 SE Everett Mall Way.

All three suspects were released from custody Wednesday after being interviewed. They are a 16-year-old from Everett, a 21-year-old from Shoreline, and a 29-year-old from Seattle. Police aren’t releasing their names pending potential charges.

The stands’ owner on Wednesday denied any wrongdoing.

The arrests about 1 p.m. Wednesday were the culmination of a two-month investigation by undercover detectives, Snell said. The investigation began after people lodged complaints with the cops.
